Fuse is often used in low-voltage distribution network and power traction system short circuit protection and serious overload protection, when used, fuse should be in series in the protected circuit, normal work, the melt of the fuse is equivalent to a wire, and when the circuit short circuit failure, the melt can quickly fuse off the circuit, play a role in protecting the line and electrical equipment.

The principle of the fuse is relatively simple. The current overload will heat the filament inside the fuse to exceed the melting point of the filament, causing melting. Once the fuse is disconnected, the current is turned off and the circuit is cut off. This process is automatic and usually takes only a few microseconds to complete.

The melt is blown at the crimping or other parts, and there are generally no serious burn marks. The reasons for this may be: the melt section is too small; The melt has scar defects during installation; The fuse porcelain tray is not fixed; The melt crimping is not tight; The melt runs too long and produces a copper-aluminum oxide film, which increases the contact resistance.

High-voltage fuses are simple protective appliances, which are used to protect electrical equipment from overload and short-circuit currents; According to the installation conditions and uses, choose different types of high-voltage fuses, such as outdoor drop type, indoor type, for some special equipment high-voltage fuses should be selected special series; What we often call fuses is a fuse.

Fuse in low-voltage distribution system is a kind of electrical appliance that plays a role in safety protection, fuse is widely used in power grid protection and electrical equipment protection, when the power grid or electrical equipment short circuit fault or overload, can automatically cut off the circuit, to avoid electrical equipment damage, to prevent the spread of accidents.

During the normal operation of electrical equipment, the fuse should not be blown out; In the event of a short circuit, it should be fused immediately; When the current changes normally (such as the motor starting process), the fuse should not be blown out; When the electrical equipment continues to be overloaded, the fusing should be delayed. The rated voltage of the fuse should be greater than or equal to the rated voltage of the circuit.

The high-voltage drop fuse adopts single-phase operation of an insulated rod and does not allow operation with load. It has been found through practice that when the phase is mistakenly pulled with load, most cases are similar to disconnecting the parallel loop or loop, and the disconnection voltage is low, so strong arcing does not occur. When the second phase is pulled open with load, the break voltage is higher because the break voltage is the line voltage.

Users in the logistics industry can log in to China Industrial Electrical Appliance Network to register as members and publish logistics information. China Industrial Electrical Appliance Network provides better service support for our customers, and hopes that customers in the logistics industry will release true and reliable logistics information based on the principle of honesty and credit. Now when you think of "logistics", you should think of the logistics and transportation problem of Double 11, in fact, logistics is a word imported from Japanese materials.

1. The specifications of the fuse should meet the requirements of the protected lines and equipment; The melt shall not be cut small or used together, and metal wire is strictly prohibited instead of fuse.
2. The melt should have a protective cover. Tubular fuses shall not be used without tubes; Melters with filling materials shall not be modified for use.

In order not to fuse the fuse when the motor starts, the rated current of the selected fuse is 1.5~2.5 times larger than the rated current of the motor, so that even if the motor is overloaded by 50%, the fuse will not blow, but the motor will not burn out in 1 hour. Therefore, the fuse can only be used as short-circuit protection for motors, wires, and switchgear, and cannot play the role of overload protection. Only equipment such as thermal relays can be used as overload protection for motors.

When removing the DC control fuse, it should be positive first, then negative. When installing the DC control fuse, it should be installed first negative and then positive. The purpose of this is to prevent parasitic circuits and avoid malfunction of the protective device. The fuse should be installed and taken quickly, not continuously turned on and off, and there should be a period of time between removal and reinstallation (should not be less than 5 s).
